I avoid editing the grub.cfg file for three reasons: 1 - I don't know what I'm doing, if magic is needed the install/upgrade should be the magician. The average users knows way less than I do about system setup 2 - The last time I did the system wound up being a totally unbootable recovery adventure. See #1 3 - every kernel upgrade seems to rebuild the config file, making change a brief success.
3 is completly untrue
until now after kernel updates grubby is adding the new one to grub config and taking any chnage you made in the previous one to the new entry
only "grub2-mkconfig" is creating a complete new config with all this submenu crap and so on for kernel params "/etc/default/grub" is your friend here
